To ItZZ 1011/0111, it mil/y concern.-

Be it known that we, GEORGE Wear and ARTHUR WRAY, subjects of the King-.of Great Britain, and residents, respectively, of 3i Quarry street and6 Thorn street, Keighlcy, ill the county of York, England, have inventedcertain new and useful Improvements in Apparatus for Spraying andConditioning Yarns, of which the following description, together withthe accompanying drawings, is a specification;

This invention relates to apparatus or mechanism for use in subjectingyarns or threads of fibrous substances to the actions of water ormoisture in order to bring said substances into any desired state ofhumidity that occasion may require for purposes Well understood; and theobject of our said invention is to provide means or apparatus that shallbe continuous in action and that shall subject all the outer surfaces ofthe cops, bobbins, or spools of yarn treated thereby to any desired orlimited extent that circumstances may necessitate and that withoutrequiring any attention on the part of the operative further than theadjustment of the apparatus to carry out the process with regularity andprecisioin 111 the accompanying sheets of drawings, which areillustrative of our said invention, Figure 1 is a side elevation, partlyin section, of apparatus or mechanism constructed in accordance with ourinvention. Fig. 2 is a sectional side elevation of said apparatus asseen in the direction opposite to that shown by Fig. 1. Fig. 3 is a viewof the apparatus as seen from above.

In carrying our invention into eilect we make use of a receptacle orchamber a, which may be open or partly open at the top, as shown, or itmay be entirely inclosed. At the lower part oi this chamber we arrange atraveling apron b, which takes over the roller 0 at one side of themachine and over the roller d at the other side of said machine. Thisroller d has ribs (1, which intercede between the cross-pieces b of theapron b, so that as this roller d is rotated through the train of wheelsf f f by the driving-pulley 9 said apron It is caused to move in thedirection indicated by the arrow 2 around the roller 0.

The apron b is preferably constructed by side chains h it, formed toreceive the crosspieces I), which are pivoted at each end upon them insucha manner as to be free to rotate,

so that in traveling through the chamber a on coming into contact withthe contactpiece 1c said rollers b" will be rotated through a spacesu'tlicient to turn the cops, bobbins, or spools m resting upon andcarried by them, through about half a revolution. Thus as said cops,bobbins, or spools m are approaching the contact-piece k one-half oftheir outer surfaces will be exposed so as to be subjected to thehumidifying actions of the spray 1), while on reaching said piece It therollers b, carrying same, will be revolved to rotate said cops, bobbins,or spools m, so as to cause them to present the other parts of theirouter surfaces for the actions of said spray p as the apron b continuesin its path of motion,until the roller (1 is reached, where the path ofthe apron is such as to allow the cops, bobbins, or spools m to falltherefrom on their treat ment being finished into the receptacle gbeneath. i

The guide-roller c is mounted in bearings r T, which haveadjusting-screws s to regulate tlt.e tension of the apron b by movingsaid roller 0 closer to or farther from the roller d. The driving-pulleyg is mounted to run loosely upon its shaft g and has a clutch-pin g forengaging with a clutch-piece on the wheel f when motion has to betransmitted thereto and to the roller d, and consequently the apron b.The driving-pulley 9 also transmitsmotion to wheel 15, W1 .ich carriesthe cocentric for operating the piston t of the pump t, so th at thecondensed or accumulated spray which falls into or is gathered by thetray u beneath the apron b and isv drained by the pipe 3 into thereceptacle u is raised by tl is pump t into an accumulator o, having apressure-gage o, from which it is allowed to escape through thespray-producers to at any desired pressure, thus producing a finer orcoarser spray, as circumstances may require, by having the water toissue at a higher or lower pressure.

The pressure at which the contents of the accumulator e (which isillustrated partly in in section by Fig. 1 so as to show the arrangementof the interior discharge-pipe '0) may be kept 'is regulated by theadjustable weight at, mounted on the lever-arm of the escape-valve m.The farther said weight :2 is from the fulcrum of said lever 11: thegreater will be the pressure in the accumulator o to overcome same whenescaping through said valve on.

It will be readily understood that the valOO rying of the position ofthe weight 90 will have the effect of varying the pressure in theaccumulator without in any manner requiring a varying in the motion ofthe apron and, through the connecting mechanism, the pumping device.Ilencc tie pressure may be regulated wl ile the machine 01' apparatus ismoving at a uniform speed.

From the foregoing description it will be seen that on the operativeplacing the cops, bobbins, or spools of yarn upon the apron b at thepart over the roller 0 they will be carried thereb through the chamber aand that the rate of speed of such travel, together with the conditionsof the spray p acting upon them, will determine the amount of humiditythat is transmitted to them. Hence by regulating the speed of the apron-I) (as by adjusting the charge-wheels f f) and by regulating thepressure of the water passing through tle spray-producers w (as byadjusting the weigl .t m on the arm 3:) tie desired results or actionsof same upon the yarn under treatment is effected.

It is to be understood that the expression contained yarn used hereinrefers to yarn wlich is contained on cops, bobbins, spools, or othersimilar container.

Such being the nature and object of our invention, what We claim is 1.In apparatus of the class described, a

spray-producer, a traveling apron, means for transmitting motionthereto, said means having an independent movement to cause the entireouter surface of the contained yarn to be subjected to the action of thespray, means, including a pump, for supplying a liquid to saielspray-producer, and means independent of the pump for controlling thepressure of the liquid.

2. In apparatus of the class described, a traveling apron, change-Wlieel-drivin g me ohanism for transmitting motion thereto so thatthe rate of speed thereof may be regulated, and means for causing aspray of Water or liquid to fall upon said apron under pressure, saidmeans including independent liquid-supplying and pressure-controllingdevices, the apron having an independent movement to cause the entireouter surface of the contained yarn to be subjected to the action of thespray.

3. In apparatus of the class described, a traveling apron,sprayproducing devices mounted ab ove said apron, the apron having anindependent movement to cause the e-n tire outer surface of thecontained yarn to be subjected to the action of the spray, an accu imulator, means for supplying water or liquid to said accumulator, andinde endent means for controlling the supply of liquid to theaccumulator.

, 4. In apparatus of the class described, a traveling apron,sprayproducing devices mounted to operate in conjunction with saidtraveling apron, the apron having an independent movement to cause theentire outer surface of the contained yarn to be subjected to the actionof the spray, an accumulator, means for supplying Water or a liquid tosaid accumulator, and means, intermediate said accumulator and saidsupply means, for controlling the pressure of the liquid in saidaccumulator.

5. In apparatus of the class described, a traveling apron havingrotatable rollers, means whereby said rollers are rotated at one part oftheir path of motion and means where by Water or a liquid may be sprayedover said apron during its traveling movements substantially as setforth.

6. In apparatus of the character described,

a spraying device, and means movable through the spraying zone forpassing conained yarn into and through said zonesaid means having anindependent movement to cause the entire outer surfacepf the containedyarn to be subjected to the spraying action.

7. In apparatus of the character described, a spraying device, meansmovable through the spraying zone for passing contained yarn into andthrough said zone said means having an independent movement to cause theentire outer surface of the contained yarn to be subjected to thespraying action, and means for controlling the movement of the containedyarn through said zone to control the extent of spraying action to whichthe yarn is subjected.

8. In apparatus of the character described, a spraying device and meansfor.supplying liquid thereto under pressure, means movable through thespraying zone for passing contained yarn into and through said zone saidmeans having an independent movemcnt to cause the entire outer surfaceof the contained yarn to be subjected to the spraying action, and meansfor regulating the pressure of said liquid.

9. In apparatus of the character described, a spraying device, and atraveling apron adapte d to carry contained yarn through the sprayingzone, each of the yarn-containers being given a motion on its axisduring its passage through said zone.
